AutoTestGPT: A System for the Automated Generation of Software Test Cases based on ChatGPT

Abstract

The design and generation of software test cases stand as critical steps in elevating the levels of automation and intelligence in software testing. Given the robust natural language understanding and code generation capabilities of ChatGPT, this paper, after extensive research on ChatGPT’s applications in the field of software testing in recent years, introduces a ChatGPT-based software test case auto-generation system named AutoTestGPT. This system leverages ChatGPT as its intelligent engine to conduct dialogue training. It extracts key information from structured testing requirements, leading to the formulation of comprehensive testing plans. Subsequently, it systematically generates corresponding test cases according to the devised plans. Finally, the system executes the generated test cases, conducts result verification, and generates detailed testing reports. Experimental results within the API testing framework and test case generation demonstrate that the API testing framework generated using AutoTestGPT exhibits high usability. In comparison to manually coding and constructing test frameworks, the time required for test framework generation is reduced by over 70%. AutoTestGPT demonstrates high efficiency in handling complex test case generation tasks, thereby enhancing the automation and intelligence levels in test case generation. This system lays a robust foundation for the establishment of intelligent systems in software testing for the future.
